The answer would be 30 if u use the gcf
As the general formular for a straight line is
m represents the gradient
c represents the point at which the line crosses the y axis.
Therefore you simply plug the numbers into the equation.
You can work out whether 2 lines are perpendicular by multiplying their gradients. The product of the gradient of perpendicular lines will always be -1.
If lines are perpendicular, M1× M2 = − 1
So you can rearrange the equation to get M2=-1/M1.
As they perpendicular they have to intercept at the same point on the Y axis therefore you get the equation
13 should be b and
14 is a because geometric mean to have a common ratio
Answer:
12%
Step-by-step explanation:
50 - 44 = 6
6/50 = .12
.12 x 100 = 12% decrease
